- Software ready: roaster prepared for Artisan and Cropster connection.
- Automation-ready: software can control burner, drum and airflow for automatic roasting according to preset recipes (automatic version).
- Dual thermocouples: bean temperature and exhaust temperature as standard.
- Underpressure measurement: electronic drum underpressure measurement included (CMS-6, CMS-12, CMS-30).
- Certified safety: Emergency Stop and safety devices according to CE standards.
- Separate cyclone: external cyclone with user-friendly emptying system.
- High insulation: high temperature insulation for energy-efficient and quiet operation.
- Easy maintenance: design focused on straightforward cleaning and access to service points.
How it works
- Load green coffee into the drum (4 to 12 kg per batch).
- Set burner power, airflow and drum speed on the control panel (or via software in the automatic version).
- Monitor bean and exhaust temperature to follow your roast profile.
- Discharge roasted coffee and start cooling while the next batch is already roasting.

FAQ – Frequently Asked Questions
Is the CMS-12 compatible with Artisan and Cropster?
Yes. The roaster is ready to connect to roasting software such as Artisan or Cropster. In the automatic version, the software can also control the burner, drum and airflow for automatic roasting according to preset recipes.
Can I roast and cool at the same time?
Yes. Thanks to 4 independent motors, roasting and cooling run in parallel. You can start cooling one batch while the next batch is already roasting, increasing hourly output.
What is the minimum and maximum batch size?
The CMS-12 is designed for batches from 4 kg up to 12 kg of green coffee. This range allows both profile testing and full production roasting on the same machine.
How energy efficient is the roaster?
The premix burner with modulated flame and high temperature insulation provide efficient heat transfer and reduced gas consumption compared to conventional systems.
What maintenance is required?
Regular cleaning of the drum, cyclone and exhaust paths is recommended to maintain performance and safety. The design allows easy access to key components without special tools.
Designed for roasteries that need stable 12 kg production, clean combustion and repeatable roasting curves without complicating daily operations.
